Nursing Elites

1. A 36-year-old woman complains of reflux symptoms and intermittent diarrhea. The diagnosis of gastrinoma is suspected so a fasting serum gastrin is obtained and found to be 280 pg/mL (normal <115 pg/mL). An abdominal CT is negative. What would you do now?

• A. Refer her for an exploratory laparotomy
• B. Measure serum gastrin in response to secretin infusion
• C. Treat her for H. pylori
• D. Obtain a dedicated small bowel series

Correct answer: B

Rationale: The next step after finding an elevated fasting serum gastrin level is to perform a secretin stimulation test. This test helps differentiate between gastrinoma and other causes of elevated gastrin levels, such as proton-pump inhibitor therapy or H2 antagonists. In gastrinoma, the serum gastrin level should further increase after secretin infusion, while in other conditions, the levels would not significantly rise. Exploratory laparotomy would be premature without confirming the diagnosis. Treating for H. pylori is not indicated as the diagnosis of gastrinoma is under consideration and not Helicobacter pylori infection. A dedicated small bowel series is not the next appropriate step in this scenario.

2. The client with newly diagnosed hypertension is being taught about lifestyle modifications. Which recommendation should be made?

• A. Increase your intake of saturated fats.
• B. Limit your alcohol intake to two drinks per day.
• C. Engage in at least 150 minutes of moderate exercise per week.
• D. Use table salt liberally to season your food.

Correct answer: C

Rationale: Engaging in at least 150 minutes of moderate exercise per week is a key lifestyle modification recommended for individuals with hypertension. Regular exercise helps manage blood pressure, improve cardiovascular health, and overall well-being. It is important for the client to adopt a healthy lifestyle to control hypertension and reduce the risk of complications.

3. A client with a new diagnosis of myasthenia gravis is prescribed pyridostigmine (Mestinon). Which instruction should the nurse include in the client's teaching?

• A. Take the medication with food to prevent gastrointestinal upset.
• B. Take the medication 30 minutes before meals.
• C. Avoid dairy products while taking this medication.
• D. Take the medication at bedtime.

Correct answer: B

Rationale: The correct instruction for a client with myasthenia gravis prescribed pyridostigmine (Mestinon) is to take the medication 30 minutes before meals. This timing is crucial as it helps improve muscle strength for eating and swallowing. By taking the medication before meals, the client can experience enhanced muscle function during mealtime, which is especially important for managing the symptoms of myasthenia gravis. Choices A, C, and D are incorrect. Taking the medication with food may decrease its effectiveness, avoiding dairy products is not necessary, and taking the medication at bedtime does not coincide with the optimal timing for enhancing muscle function during meals.

4. A client with newly diagnosed hypertension is prescribed enalapril (Vasotec). Which instruction should the nurse provide to the client?

• A. Increase your intake of potassium-rich foods.
• B. Report any persistent cough to your healthcare provider.
• C. Take the medication with a full meal.
• D. Avoid grapefruit juice while taking this medication.

Correct answer: B

Rationale: The correct instruction for the nurse to provide the client taking enalapril (Vasotec) is to report any persistent cough to their healthcare provider. Enalapril can cause a side effect of a persistent cough, and it is essential for the healthcare provider to be notified if this occurs to evaluate the need for a medication adjustment or change. Choices A, C, and D are incorrect. Increasing potassium-rich foods is not specifically related to enalapril use; there is no requirement to take enalapril with a full meal, and avoiding grapefruit juice is more relevant for medications metabolized by the CYP3A4 enzyme, not typically for enalapril.

5. The nurse is caring for a client who is receiving chemotherapy. Which laboratory result indicates that the client is at risk for infection?

• A. Hemoglobin level of 12 g/dL.
• B. Platelet count of 150,000/mm3.
• C. White blood cell count of 2,000/mm3.
• D. Serum creatinine level of 1.0 mg/dL.

Correct answer: C

Rationale: A white blood cell count of 2,000/mm3 is low and indicates leukopenia, which increases the client's risk for infection. Hemoglobin level and platelet count are not directly indicative of infection risk. Serum creatinine level is related to kidney function, not infection risk.
